DRAFT-GEAR FRICTION-PLATE HOLDER.

Appiication inea March 19, 1923.

by declare that the following is a full, clear,

and exact description of the same, reference being had to the accompanying drawings, and to the numerals of.` reference marked thereon, which form a partl of this specication. l

This invention relates to a drafty gear provided with an improved holding means for retaining the friction elements of the draft gear in place within the drawbar yoke and separated from the car draft sills.

It is an object of this invention to provide a draft gear with flanged friction plate holders preventing the friction plates from acting on the draft sills of a car to wear the same out. y

It is also an object of the invention to provide a draft gear wherein the friction elements when engaged in flanged holders are adapted to be readily mounted in place within a drawbar yoke.

Another object of the invention is to provide an improved draft gear adapted to be readily mounted in the standard space provided therefor in a car without requiring any change in the standard structure.

It is an important object of this invention to provide an improved draft gear construc tion adapted to be installed in a standard railway car construction and supported in place by a carry iron adapted to be secured to the draft sills of a car. l

Other and further important lobjects of this invention will be apparent from the disclosures in the specification and the accompanying drawings:

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. l

On the drawings:

Figure 1 is a fragmentary sectional top plan view of the draft sills of ak railway car having mounted therebetween an improved draft gear partly shown in section and embodying the principles of this invention.

Figure 2 is a longitudinal sectional view taken on line 2-2 of Figure 1.

of the draft sills and the draft gear with the sill plate removed.

Figure l is an enlarged transverse section taken on line 4 4 of F igure 2.

Figure is a section similar to that illustrated in Figure 2 of a modified form of a draft gear.

Figure 6 is an enlarged transverse section taken on line 6-'6 of Figure 5.

As shown on the drawings:

The reference numeral 1 indicates a pair of railway car draft sills of channel iron construction which are mounted longitudii nally on the car. A sill plate 2 is mounted on and connects the upper flanges of the draft sills. Secured to the lower flanges 3 of the draft sills by means of bolts 1 is a carry iron 5 comprising a broad plate or bar the ends of which are bent to form flanges 6 which project upwardly beyond the lower sill flanges 3.` The middle portion of the carry iron is pressed or formed to afford an elevated rest or guide 7. The carry iron 5 is located below the point wherethe shock absorbing device ofthe draft gear is to be positioned.

Secured to the inner face of each draft sill 1 are front and rear blocks or castings 8 and 9 respectively, which are riveted to the 'sills and positioned at thefront and rear respectively of the carry plate 5 to afford a` space into which the shock absorbing device of the draft gear is adapted to fit. r.lhe castings 8 and 9 are provided with inwardly directed flanges 10 and 11 respectively, which y serve as stops or abutments for the shock absorbing device.

The shock absorbing device comprises a series of groups of similar friction plates 12 lwith the plates in each group placed face-to applied to a coupler or drawbar 13. rlhe two middle groups of friction plates 12 are separated by a double convex spacer block 14. The outer groups of friction plates are separated by double concave separator blocks 15. Positioned, against the outer friction plate 12 of eachl end group of plates is the convex inner face 16 of a follower block 17.

The lvarious groups of friction plates 12, the separators 111 and 15, and the follower blocks 17 are all disposed between a pair of channel holder plates 18 each having integral longitudinal side flanges 19 and an integral longitudinal central guide shoe or boss 20 which is shorter than the length of the holder plate. As illustrated in Figure 3, each holder plate 18 kis cut away at each end to afford a notch or recess 21 having inclined side edges converging toward the middle of said holder plate. The guide shoe 2O on the lower holder plate is adapted to rest on the lower bar of a yoke 22 which is engaged around the holder plate 18 and the shock absorbing mechanisms contained therebetween. rlhe ends of the yoke 22 are integral with the drawbar 13. rPhe yoke 22 is positioned to ride on the carry iron guide 7, as illustrated in Figure 4. rlhe follower blocks 17 are adapted to abut against the front and rear stop flanges 10 and 11 of the castings 8 and 9. The front follower block 17 is also in Contact with the drawbar 13, while the rear follower block 17 is seated against the bight of the yoke 22. i

As illustrated in the drawings, the friction plates 12, together with the follower blocks 17 and the separators 14 and 15, are all positioned between the holders 18. The holders 18are disposed within the yoke 22 and between the stop flanges 10 and 11. This arrangement prevents any wearing action by the shock absorbing plates on the draft sills 1. Inasmuch as the holders 18 form a part of the draft gear mechanism, the Jfriction plates 12 may be made to fit transversely `therebetween so that there will be no substantial space for movement between the ends of the friction plates and the flanges 19 of the holders 18. It will thus be noted that the improved draft gear construction of this invention is so Ydesigned that the wear on the draft sills is eliminated due to the use of theflanged holders 18 between which the shock absorbino' or friction elements are mounted.

Figures 5 and 6 illustrate a modified form of a draft gear mechanism similar in4 construction to that illustrated in Figures 1 tov 4 inclusive.

nated by corresponding reference numerals'. The carry iron 23 is formed with an elevated rest or guide 24 on which the yoke 22 is supported.

ln this form of device only one friction plate holder 25 is provided. The holder 25 is provided with upturned flanges 26 be- The parts that are similar .to parts shown in Figures 1 to 4 are desig- The holderv sirable that the draft gear be adapted to be mounted in position from below and accessible to permit of replacement and repairs. In the improved construction of this invention the` friction plates 12, the separators 14 and 15, and the follower blocks 17 are placed'in posi-tion between the two holders 18. This being done, the shock absorbing elements and the holders are pushed into the yoke 22 completing the .assembly of the draft gear. The assembled draft gear is now jacked up and raised into place between the car draft sills 1 with the holders containing the shock absorbing elements positioned between the stop flanges 10 and 11, as illustrated in Figure 1. rlhe carry iron 5 is next secured in place to support the yoke 22 in proper position between the draft sills 1. The draft gear may thus be mounted in place as an assembled unit without requiring any changes or alterations of the standard parts of the car structure. The draft gear illustrated in Figures 5 and 6 is assembled and mounted in position in a mannerv similar to that described in connection with the device covered by Figures 1 to 4 of the drawings.

l am aware that numerous details of construction may be varied through a wide range without departing froml the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as'my invention:

1. The combination with a pair of spaced railway vcar draft sills, of spaced stops secured thereon, a drawbar, a yoke thereon, a carry ironv secured to said sills having a raised middle portion on which said yoke is supported, a flanged holder in said yoke, and shock absorbing elements in said holder separated from the draft sills by the flanges of said holder.

2. In a device of the class described, the combination with a pair of draft sills, a drawbar therebetween, ayoke on said drawbar, a carry iron connecting said sills and formed with an elevated support upon which the yoke rests, holders in said yoke, guide shoes formed on said holders, flanges formed on the longitudinal edges of said holders with the flanges of one holder directed toward the flanges of the other holder, and shock absorbing elements in said holders and separated from the draft sills by said holder flanges.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
